Point-source and area-wide field studies of pyriproxyfen autodissemination against urban container-inhabiting mosquitoes

•Point-source and area-wide study conducted in Aedes albopictus endemic areas.•Pyriproxyfen autodissemination from treated to untreated areas was detected.•Point-source was better than area-wide treatment for autodissemination.•Autodissemination up to 200m was detected.•Long exposure accumulated pyriproxyfen in autodissemination samples.
